About the size of a cellphone, and with text flowing from top page to bottom page, these books can be read with one hand. On thin but durable paper, these books are slim and easy to pack or read on the go. "Although there are many things about this life that I do not understand, there are some truths about which I no longer have any doubt." With that introduction, Sheri Dew of the general Relief Society presidency offers a faith-filled account of what she believes, and why. She bears powerful testimony of the reality of Jesus Christ, that He cares about us personally and will do for each one of us what He has promised He will do. She discusses our individual, unique missions of mortality, reminding us who we are and who we have always been. And she expands our understanding of the happiness that comes from living the gospel, the power of families, the importance of the priesthood, the security of having a living prophet, the glory of the temple, and the transcendent blessings available to all who seek the Lord. But No Doubt About It is much more than an insightful look at foundational gospel principles. It is a stirring call to action, a motivating book that will help readers move beyond knowing to doing. Vivid stories of the author's own experiences demonstrate how these truths apply in real-world settings. "We no longer have the luxury of spending our energy on anything that doesn't lead us and our families to Christ," writes Sister Dew. "In the days ahead, a casual commitment to Christ will not carry us through. The time has come for each of us to stand tall, and then, in doing so, to stand together." Latter-day Saints across the world have come to appreciate Sheri Dew's personable style, her memorable stories, and her solid understanding of doctrine. No Doubt About It is a wonderful blend of all three, the book people have been asking for and one that will change their lives for the better. Life is filled with moments of joy, but life is also hard. It is an unmistakable privilege to be here in mortality, but the burden we carry is weighty, relentless, and laden with importance. So I pose two questions: What have we come here to do? And how will we do it?— Sheri Dew
